No global warming exists, and global cooling exists, they are two different stages of the same climate change pattern over the history of the planet.
We've left global warming in 2016 ish, and we're entered global cooling. It's about 200- 300 years cycles. Mostly driven by the sun output and volcanic activity.
Have you noticed all those volcanos in the past 3 -4 years? Those very harsh winters in US/ Europe?
It's not man made at all. The sea and forests absorb CO2 and regulates. More CO2 leads to faster vegetation growth and sea calcification. The earth is a self regulating system.
Stopping pollution is a different topic, it's an obvious topic, we should not pollute. Pollution has a tiny impact on the climate, vs. the sun.
It was pretty much mainstream science in the 80s until taxes were needed and you had to find a cause for scientists, gubmints and the likes to pretend to address a problem (and then need even more taxes/funding). It's quite sad actually, how science has totally lost the plot, and real scientists are being shunned.
Anyway, this is a powerplay for the future, when you understand what this future will be. Most investors have no idea. But you can see the development of hydroponic project shows the VERY smart money has taken notice.
